It will save time in the field when trying to do any testing. Sending commands from a phone is already sort of a pain. And when you need to send additional ones, depending on the time of day, they don't or wont go through. At times having them stack up in Que. Plus the additional cost for the additional packets... I am not sure how this will work. Seems easy enough. Have each packet automatically verify the change or something so the extra packets are not needed.
